The effect of damask rose extract on sleep quality in patients undergoing angiography admitted to cardiac care unit

Aim. This study aimed to examine the effect of damask rose on sleep quality of patients undergoing angiography admitted to cardiac care unit.
Background. Sleep is one of the basic human needs and determine the health and recovery. Most patients hospitalized in cardiac care unit experience some degrees of sleep disorder.
Method. In this double-blind clinical trial¡ 90 patients were randomly allocated to experimental (n=45) and control (n=45) group. Data collection instrument consisted of demographic data and St. Mary''s Hospital Sleep Questionnaire (SMHSQ). In experimental group¡ damask rose extract was given by oral route¡ 15 drops every 8 hours. The patients in control group received placebo by oral route¡ 15 drops every 8 hours. Data were collected¡ before and after intervention and were analyzed in SPSS 16 using descriptive and inferential statistic.
Findings. Both groups were homogeneous in terms of demographic characteristics. There was no statistically significant between groups in terms of sleep quality¡ but¡ a statistically significant difference was found between sleep quality¡ before and after intervention¡ in each group.
Conclusion. A significant difference before and after treatment in both groups can show that any effort by the nursing staff even drop placebo may have an effect on sleep quality. Damask rose extract was not found to have a significant effect on quality of sleep in control group compared with the control group. It is recommended to replicate the study with longer duration of intervention and/ or changing the method of damask rose administration.
